A young common grass snake
depends where you are but if you where in brittain i would have to say a grass snake
A mallard is a bird that has an iridescent green head and brown on the body. The ring necked pheasant is another bird with a brown body, and an iridescent green head.
I have know clue but i wanna know cause my brother saw one in our barn he described it as gray body black head and a lil bit to 17 ft!!
Ring neck snake
the natural colouration of a budgie is a green body with a yellow head
not exactly, it is just the color
Sounds like a ringneck snake, they are completely harmless and some of the most beautiful (in my opinion) of the North American snakes.
a coin
If you saw one it depends where you live, but it could be one of the following: green tree snake: http://las.new-England.net.au/wp-content/uploads/2007/03/images20070304-035-treeSnake-sml.jpg http://www.tvwc.org/AssetsGreenTreeSnake.jpg green tree python: http://www.kingsnake.com/ihs/I.H.S.%202005%20PHOTO%20CONTESTHeat%20pits%20of%20the%20green%20tree%20python%20-%20Michael%20D.%20Kern%20-%20IN%20CAPTIVITY,%20SM.jpg rough green snake: http://www.wilddelaware.com/wp-contentrough-green-snake-11832.jpg natal green snake: http://api.ning.com/files/L1ySGyMwLZ3hID057bBHbPN6Eqw8ML160RN4P6rDPxM_NatalGreenSnake.jpg Asian green snake: http://www.dekayi.info/R_I_P_%20Green%20snake_filestree2.jpg Hope this helps.
snakes can be all colours except blue and purple
sounds like a rattle snake. Does the head come to a point and you can tell the difference between the body and head? If so it is a rattlesnake.
probably a coral snake or something
